1. A method of additive manufacturing using at least one processor, the method comprising:
determining a first slicing layer of a three-dimensional (3D) model of a 3D object;
determining a second slicing layer of the 3D model based on the first slicing layer, the second slicing layer being immediately subsequent to the first slicing layer;
determining a thickness of the second slicing layer and an orientation for a third slicing layer of the 3D model based on a difference between the second slicing layer and the first slicing layer, the third slicing layer being immediately subsequent to the second slicing layer; and
determining a print head trajectory, wherein said determining the print head trajectory comprises controlling an orientation for a print head for printing along a contour of the first slicing layer, the second slicing layer or the third slicing layer.
